Lam Patent No. 103,121, dated Ma 17, 18 70 IMPROVEMENT 11v AIR-COMPRESSING APPARATUS.

" The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

; Be it known that'I, BENJAMIN T. BABBITT, of the city, county, and State of New York, have invented anew and useful Improvement in Apparatus for Oompressing Air, of which the following is a full, clear,

" and exact description, reference being had to the acair, and produce a partialcompression ,within a supply-chamber, and", secondly, by making a fall operate,

on a tloat within a receiver that draws its charge of air, in the fall ofthe foat, from the supply-chamber, and in which said air is further compressed by the rise of the flout acting, as a ram, the whole being antomatic in its action, substantially as hereinafter de-' scribed. a

, Referring to the accompanying drawing.- A and A represent two modifications: of waterpipes with difi'erently shaped air-pipes B B arranged toenter them from abo've, either or both of which may be used, the water, that'ma'y be derived from any suitable fall, causing, as it passes down through the the outer pipeA or A, air to, be sucked through the pipe B or B, and to enter, together with the water, a trap, 0., in which the water rises, while the air that is partially compressed passes to a supply-chamber, D. This trap D is automatic in its action, by arranging within it a float, E, of any, suitable description,'and connecting'the same with" an, outlet-valve, F, preferably of balance construction, and that may be made of ordinary ventilator form, duplicated on reverse sides of its chamber. p

The float E, in risirg above-a central level, opens the valve F, and allows of the entering water to run off, while, in falling below such level, it closes the valve, and allows of thp water rising in the trap to repeat or continue the compression of the air sucked or drawn in with the water, which air passes into the 2, a face view of one ofthe'valves used I supply-chamber D. In this way a fixed partial com;

pression of the incoming air is kept up,

1 G is an additional pipe, down which, on the open-iv ing of a valve, H, a fall of water is made to pass and enter from belowa receiver, I. that is also provided at or near its bottom with a discharge-valve, J.

These valves H and J may be of similar construction to' the valve F, or of any other suitable description, but it is preferred to have them balance-valves.

Within the receiver I is a float, K, that, .in rising,

by the admission of water through the valve H, acts as a ram, and compresses the air in the receiver from whence it may escape or be led, as required, by the opening of a valve, L, which, if desired, may be weighted. The air is supplied to the receiver I in a partially compressed condition from the supply-chamber D.

This occurs during the fall of the float K, and said air is prevented from returning or being compressed back into the supply-chamber during the rising of said pipe float by a check-valve, M, arranged within the whichconnects the chamber D and receiver 1.

As the-float K completes its upward or com pressing stroke it strikes levers b'b, which are connected by rods 0 c to valve-0perating levers d (I, and closes the inlet-valve H, and opens the discharge-valve J This allows the water in the receiver to run out and shuts off all further admission of water to the receiver, so 1 that the float falls, the receiver becomes charged with a fresh supply of air from the supply-chamber D, and

on the float K falling to a certain level it strikes the levers d d, and reverses the action by again opening the inlet-valve H, and closing the outlet-valve J, whereby .a renewed compression of the air takes place in the receiver I. Such action is repeated as long as the fall of water is kept running, and a perfect auto-.

matic action secured to the apparatus.

What is here claimed, and desired to be secured by Letters Patent, is-

The combination of one or more water-pipes A, airpipes B, and the trap O, with its valve and float, the chamber D, receiver I, water-supply pipe 1G, inlet and outlet-valves H and J, and the check-valve, M, sub stantially as specified.
